Prevent v 1.0 is a freeware app which runs on all Windows. If you don't want anyone deleting or renaming or messing around with your data, maybe your younger sibling, then Prevent may be able to help you.

The installer only places the Prevent folder in the system Program Files folder. A desktop shortcut will also be created. To run the program, click on Prevent. Set your Hot key to stop Prevent.
